At check-in the unmanned machines said QR code was invalid so had to queue for over an hour to check in bags

i used to fly aer Lingus regularly but due to price - poor seating etc i have been using other carriers - i now have aer lingus in my state and the price is always the highest - i have flown to Ireland 11 times in last 24 months and have not used Hartford because of price

Nicest staff I’ve experienced on a plane! Good food, great entertainment, and they gave out little blankets that my kids loved. All in all, great experience.

I dont fly them much anymore. Other carries offere better pricing and better seating options

This flight was of exactly the same high standard as the outbound leg, exactly a week earlier - except that we didn't have any food or drink because it departed at around midnight.

The Glasgow to Dublin route was very efficiently boarded, flight and landing and disembarkation were all super smooth. Dublin to JFK flight I was very pleasantly surprised overall. This was my first time on Aer Lingus and having already come off the short regional flight I was curious to know how the international flight would go. Aircraft was solid, entertainment options were better than expected, flight crew were experienced and operated like clockwork. Main entree left a little something to be desired but the snack was very tasty. Boarding and disembarkation again very smooth and pilots got us in earlier than expected. Would definitely fly again

Unfortunately the flight was delayed for 50 min. Just as we were about to board so that was a drag. The boarding was average. The bag check in process was new to us and efficient. And the flight itself was smooth- basically no turbulence.

I liked how they looked after couples by providing a row of 4 seats if available.

Food was very bad. Boarding was disorganized and messy. Crew was friendly

It was ok not that much because I always travel with Emirates airlines, Etihad, airlines, Qatar airlines compare to them food and comfortable was too low . Staff was good . Helpful

Flight was over an hour late. Boarding was really messy with long queues at the plane.

Cabin crew couldn’t be less interested. Cabin manager was the most arrogant and the rudest I’ve encountered in many years.

The worst flight ever. Sitting in plane for 4 hours delay and then they change crew. No water or food offered to any passengers including children in that time. Only 2 toilets out of 3 operating for flight with 200 passengers. Only enough food available for about 7 rows of seats depending where you sat you might be lucky. Cabin crew very unfriendly.

I bought my flight, insurance etc early and paid over £200. But had i waited until closer the time the price was much cheaper, i appreciate that it could've been more expensive but it wasn't. A better discount for booking early would be better than your current one

Big delay on run way not much explanation why, missed a important meeting in Dublin, maybe if they did nt persist measuring everyone bag over 2 cm we would have got off on time.

The lady at the boarding gate was so rude. She was challenging people being in priority and looking them up and down as if they weren’t dressed for first class. This was Ryan air priority. We all sit in the same seats. She loudly called out to embarrass a man who she believed had cheated and got in the priority line. He had a valid priority ticket and even worked for Ryanair. Also challenging visas insisting people download them until they proved on the government website it wasn’t required to print. The Ryanair employee who was challenged said she is always like this. She also pulled people from regular boarding as they were fashionably dressed and upgraded them to priority and changed their seats. That was comical. I think she felt she should be working for Emirates first class, although they would t have stood for her rude behaviour

The punctuality of f the flight was super: we left on time and arrived about 20 minutes early - and the cabin crew were both friendly and efficient. The only downside was that Ryanair appears to have resumes its old obsession with sizing cabin bags again after a long and welcome absence.

If you buy a cabin luggage, but don’t need it for your kids, so you will end up with mixed priorities. And you will need to use non priority line

Boarding waiting outside in storm and rain is not OK

Miserable staff did not want to be there. Very poor atmosphere boarding. Then just basic flight.

Flight LH760 from Germany to New Delhi, the food was excellent, the crew was fantastic, the seats in economy are usually tight these days, so I can say that the seats were Ok, the entertainment was OK because for some reason the sound is not very clear, overall I enjoyed this flight, compared to the flight (UA 962) I took with united from San Francisco to Frankfurt in this trip, that flight was horrible. Thank you Lufthansa.

The crew was caring and attentive in making my flight comfortable as I was travelling with an injury.

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

We boarded the plane and waited for 30 minutes ultimately for them to cancel the flight due to engineering issues.

Love the little chocolate bars, and consumer rights in EU regarding stepped refunds when flights are delayed.

Overall excellent service and Frankfurt Airport was very efficient and clean

It was good, but I felt a little cramp on the plane whether I was in Economy or not.

I came out early, 4 hrs before departure. The flight was changed 4 or 5 times with few minutes between new and schedule time , then 30 minutes delay, then up to 2hrs 30min delay. When I arrived in Frankfurt, no one help us to lead to the custom service. After almost 1 hour asking around then we must line up for another hour to get overnight and rebooking the next flight. We must find out how to get to the hotel by us self. The shuttle bus driver in Germany was not nice, speak German to English speaking and we must predict what she / he tried to tell us. We got up earlier and tried to not coming late to the check in and immigration procedure (we were told by the helping center that the immigration used to be over crowded) then we came there it was almost empty, then we must stay in the airport for hours not necessary. We got the coupons at the airport for compensation for waiting for delay flight for NOK 75 ( as low as 6 Euros) It is not enough to buy food at the airport price and Norwegian cost of living... How to drink a cup of cappuccino for NOK 72 when the stomach was empty for food in 16 hrs (from dinner at 6 pm the day before to 16 pm the day after) At the hotel in Frankfurt, we were offered two options spaghetti with biff or vegan food and a drink for 18 Euro. Almost 60 passenger ate the same food and I was remembered once time in former Soviet Union in 80's I travelled with Aeroflot and the passenger were stranded in the hotel for next flight and we were also offered only one choice of dinner, if we were hunger we must pay 1$ for 1 egg and another 1$ for two loaf of bread and butter. I can't believe Germany is to poor and inferior service like former USSR in 1980 decade. My good remembering of Luft Hansa disappear and changed totally by this service I got this time.

Disappointing. Too many let-downs, in delays and communication, by both Lufthansa and Discover to put in an email. I am resigned to the fact that this is what I should expect from all airlines. Unfortunately.

Because of the fog at the Frankfurt airport, our flight was delayed leaving Budapest. We only had 20 minutes to get from A23 to C13. This was quite a walk for this not-so-young anymore lady--even with the help of moving sidewalks! We also had to go through passport control and then security. Germany is extra thorough, even doing pat-downs of all passengers. We got to our gate and I knew I had been randomly selected for extra security scanning because of the "SSSS" code on my boarding pass so I wasn't surprised when he escorted me back to security to be searched some more. The boarding gate gentleman assured me that they would hold the plane. The ladies in security rushed through the scanning process as fast as they could and we were able to make our flight to Orlando. The actual flight was smooth and comfortable. The food and service were excellent. The flight crew were friendly and efficient.
